Same here. An Amtrak train would just stop at the next convenient road crossing, if there were really something preventing them from stopping at the scheduled station. Most Amtrak stations don't even have staff, or any way to prevent people from coming and going, so this would most likely involve construction on the station platform itself. That’s fairly rare but the last time I took the Zephyr headed east there was…
They can't realistically do this in Germany because the tracks are so much more busy than the US. There would more than likely be a train coming the other direction within the next few minutes, and they cannot guarantee all the people have time to vacate the track area.
For really long construction work they’ll actually build an entirely separate train station, like they did in Denver Colorado a few years back. They knew that the construction of the new station downtown would take a few years, so they built a really cheap platform a few miles away on a siding and moved all the arrivals and departures there for the duration.
